Guitar Center has donated a Fender Squier Stratocaster signed by the rather brilliant duo Rodrigo y Gabriela (along with a padded guitar case worth $50). Proceeds from the auction go to benefit the Women’s Music Summit, a three day event taking place at Musicians Institute from July 26-28, 2013. Bidding starts at $349, the auction is happening right now, and bidding is open until July 15. Shipping charges are the responsibility of the winner. You can bid on the guitar here.
